40 Claims.

1 This invention relates to lasting machines, and is herein shown asembodied in a power-operated toe-lasting machine constructed in manyrespects as disclosed in United States Letters Patent No. 2,160,846,granted on June 6, 1939 on an application of F. C. Eastmans and A. F.Pyms and in other Letters Patent hereinafter mentioned. It is to beunderstood, however, that in various novel aspects the invention is notlimited to the illustrative embodiment.

An object of the invention, among others, is to provide certainimprovements relating more particularly to the lasting of the toes offlatlasted shoes, i. e., shoes in which the marginal portion of eachupper lying over the insole extends throughout its width in generallyparallel relation to the bottom of the last. Automatic machines forlasting the toes of such shoes with toe-embracing wipers which areshaped to conform substantially to the contour of a shoe around the toeopposite to the edge of the insole require special means for positioningthe last and shoe relatively to the wipers. For purposes of thisinvention the machine herein shown is provided with means for engagingthe toe end of the last when the work is presented to the machine toposition that end of the last lengthwise and laterally, i. e., withrespect to lateral bodily movement, and with additional means forfurther positioning the toe end of the last angularly, i. e., withrespect to lateral swinging movement about an axis at the end of thetoe, by control of the heel end of the last. Such additional means, inthe construction shown, comprises a substantially V-shaped heel restwhich is moved lengthwise of the last into engagement with the upper onthe heel end of the last after the work has been presented to themachine. In order that the heel rest will thus properly position lastsof different styles, provision is afforded for determining selectivelyin accordance with the style of the last the direction of its movementlengthwise of the last and for also efiecting a predetermined bodilyadjustment thereof widthwise of the last. As illustrated, the directionof the movement of the heel rest lengthwise of the last is determined bya guide which is adjustable about an axis extending heightwise of thelast in accordance with the style of the last and for right and leftlasts, the heel rest being adjustable widthwise of the last relativelyto the guide. The proper adjustment of the guide for lasts of diiferentstyles may be indicated on a chart and will preferably be so calculatedthat no additional adjustment will be required for different sizes. Itis contemplated also that the chart will indicate the correspondingrequired adjustments of the heel rest widthwise of the last for thedifferent styles.

As common heretofore in toe-lasting machines, the wipers in the machineherein shown wipe the upper around the toe end of the last heightwise ofthe last, i. e., perform what is known as an upwiping operation, beforethey wipe the marginal portion of the upper inwardly over the insole. Inthis operation it is desirable that the wipers apply substantially equalpressures to the upper at the opposite sides of the toe, and for betterinsurance that they will act in this manner they are so controlled as topermit them to move bodily widthwise of the last in response to pressureof the upper at one side or the other of the toe on the correspondingwiper, the wipers being supported on a wiper carrier which is movablewith them widthwise of the last. To insure that in wiping the upperthereafter inwardly over the insole one of the wipers will not moveinwardly over the insole substantially farther than the other, theinvention further provides means for preventing at that time any bodilymovement of the wipers widthwise of the last. For this purpose theconstruction shown comprises means for centralizing the wiper carrierwith respect to lateral movement after the upwiping operation and forlocking it against such movement as the wipers wipe the upper inwardlyover the insole.

In order to prevent the wipers from acting too severely on the gathersor pleats which develop in the margin of the upper around the end of thetoe in the wiping of the upper inwardly over the insole, especially ifthe bottom of the toe end of the last has a convex curvature, themachine herein shown is further so constructed that after the wipershave started to wipe the upper inwardly they have an appreciablemovement progressively heightwise of the last in a direction away fromthe bottom of the last as they are moved farther inwardly. When thewipers begin their inward movements they are so positioned heightwise ofthe last as to insure against displacement of the edge of the insole,and as soon as they have wiped the upper inwardly over the extreme edgeof the insole they are moved toward the bottom of the last to increasetheir pressure on the upper before they are m ved progressively in theopposite. directionas a ove described. Substantially at the end of i theinward wipe the wipers are moved toward the bot tom of the last toincrease their pressure: on the overwiped margin of the upper. Afterhaving thus acted on the upper, in the construction herein shown, thewipers are retracted and are thereafter moved inwardly a second time inwiping engagement with the upper, the second wipe taking place withoutany progressive movement of the wipers in a direction away from thebottom of the last such as occurs in the course of the first wipe. It iscontemplated that cement will be used to secure the upper to the insole,and accordingly the margin of the upper will be held by the cementagainst any substantial retractive movement between the two wipes.

Under some conditions it may be desirable for the wipers to remain for afew seconds in pressure-applying relation to the margin of the upperafter the second inward wipe to allow more time for the cement to set.Provision is, therefore, further aiforded for automatically stopping themachine at that time in the cycle of operations or for optionallyeliminating such a stop if desired. In the construction herein shown acam-operated member arranged to act on a clutch thus to stop the machineprior to the end of the cycle is automaticallydisplaced at the propertime to prevent such stopping of the machine when mechanism controlledby the operator is set to cause such displacement of the member.

The above and other features of the invention, including variousnovel'details of construction and combinations of parts, will now bemore particularly described with reference to the accompanying drawingsand thereafter pointed out in the claims.

*In view of the disclosures in the above-men- I Lil tioned LettersPatent No. 2,160,846 and in others hereinafter mentioned, such parts ofthe machine a are common to the prior disclosures will be hereinafterdescribed only in so far as is necessary for an understanding of thepresent invention.

The machine includes a pair of toe-embracing wipers 2 (Fig. 6) forwiping the toe end of the upper heightwise of the last and forthereafter wiping its marginal portion inwardly over an insole on thelast. The shoe is presented to the machine by the operator with thebottom of its forepart in engagement with a plate 4 (Figs. 2 andlZ) thelower face of which is curved to con- 1 form approximately to suchcurvature as the corresponding portion of the bottom of the shoe mayhave. The plate thus determines the position of the shoe heightwise andwith respect to lateral or longitudinal tipping movements. It isdetachably secured by means not herein shown on a block 5 which isadjustable about anaxis extending widthwise of the shoe along guideways7 8 (Fig. 12) formed in an enlarged'lower end portion it of a Verticalrod 12, the block being thus a. adjusted by a screw 14 in the samemanner as the block it) shown in Letters Patent No. 2,385,414,

" what is commonly known as a rctarder.

granted on September 25, 1945 on an application of E. A. I-Iolmgrens.The rod i2 is vertically adjustable by a hand wheel l6 (Fig. 1) in thesame manner as disclosed in LettersrPatent No. 2,160,846.

When the shoe is presented by the operator as above described theposition of the last and shoe lengthwise is determined by engagement ofthe toe-end face of the last with a device 18 (Figs.

11 and 12) which, as hereinafter'described, clamps the marginal portionof the toe end of the upper out-spread on the wipers 2 to control it inthe lasting operation and thus has the function of This device includesa pair of fingers 2i! which are curved to embrace the toe end of the,last and further serve, regardless of the style or size of.

the last, to centralize that end of thelast and shoe laterally, i.e.,'with respect to bodily lateral movement. Substantially at thebeginning of a cycle of power'operations of the machine the shoe isclamped against the plate 4 by upward movement ofa'toe rest 22.

granted on December 10, 1940 on an application of F. C. Eastmans. Thatis, the construction is such that the toerest is forced yieldinglyagainst the shoe first with comparativelylight pressure to control theshoe and is later forced more firmly against the shoe to support itagainst the downward pressure of the wipers on the margin of the upper.As hereinafter explained, however, the time when it is thus forced morefirmly against the shoe is different from the disclosure of said LettersPatent.

Shortly after the beginning of the cycle of operations, when the toerest 22 is holding the shoe against the plate 4 with comparatively lightpressure as above described,a heel rest 24 (Figs. 2 and 4) is movedrearwardlyinto engagement with the heel end of the shoe. This heel restcomprises a V-shaped member 26 towhich is secured a similarly shapedshoe-engaging 'pad 23, and as hereinafter explained it serves not onlyto assist in supporting the shoe against lengthwisemovement, but also todetermine the position of'the heel end of the shoe laterally and Themechanism for operating this toe rest is not herein shown in.

thereby to position its toe end angularly in proper relation to thewipers. The member 26 is provided with a stem 30 (Fig. 2) extending intoa bore in a block 32 to permit the heel rest to be adjusted angularlyabout an axis extending lengthwise of the shoe, and it is held inadjusted position by a setscrew 34 threaded in the block and engagingthe stem 38. Mounted in curved recesses in the opposite sides of theblock 32 are segmental members 36 (Fig. 3) which are also mounted incurved guideways 38 formed in plates 40 at the opposite sides of theblock, these plates being secured to a holder 42 supported on the top ofa slide 44.

ed ends extending inwardly into a bore 41 in the block 32, the screwshaving also unthreaded portions extending outwardly through curved slots48 in the plates 48 and provided with hand wheels 50 fast thereon forturning them. It will be evident that through the provision of thesegmental members 36 and the guideways 38 the block 32 and the heel rest24 are adjustable upwardly or downwardly about an axis extendingwidthwise of the shoe to assist in positioning the heel rest in thatrespect in proper relation to shoes of diiferent styles. After suchadjustment the block and the heel rest, are secured in adjusted positionby the screws 46, the hubs of the hand wheels 58 cooperating with thescrews to clamp the segmental members 36 firmly against the plates 40.

Extending downwardly from the holder 42 into a bore in the slide 44 is astem 52, so that the holder and the parts supported thereon may beadjusted about an axis extending heightwise of the shoe. The holder issecured in adjusted position by a clamping finger 54 (Fig. 2) whichextends into a recess 56 in the holder and engages a horizontal face 58formed on the holder, the finger being forced down against the face 58by a screw 60 threaded in a block 62 which is secured to the slide 44.This slide is mounted for rectilinear adjusting movements in directionswidthwise of the shoe on a guide 64 which is fast on an underlying plate66, and it is secured in adjusted position by a thumb screw 68 threadedin the slide and arranged to bear at its inner end against the frontedge of the guide 64.

The plate 66 is supported on the top of a block III which is engaged andpartially supported underneath by a plate 12 secured to a bracket 14fast on thefront of the frame of the machine. Rotatably mounted on astud I6 fast on the plate 66 is a roll I8 which lies in a slot 80extending widthwise of the shoe in the block 10. Upon movement of thisblock, therefore, in a rearward direction it acts through the roll I8 toimpart rearward movement to the plate 66 and thereby to move the heelrest rearwardly into engagement with the heel end of the shoe. Suchmovement is imparted to the block by a pair of rods 82 slidingly movableinthe frame of the machine and operated by mechanism not herein shown indetail but which may be assumed to be of the same construction asmechanism shown in the previously mentioned Letters Patent No. 2,160,846for operating corresponding rods therein shown. The rods 82 in theconstruction herein shown comprise telescopic parts 84 and 86 (Fig. 2)relatively adjustable to position the heel rest preliminarily foroperation on shoes which differ substantially in size, in accordancewith the disclosure of Letters Patent No. 2,245,580, granted on June 17,1941, on an application of F. 0. East- Threaded in the segmental members36 are screws 46 which have unthreadwill be required for mans. Thesetelescopic parts are shown as dlfferently adjusted in Fig. 4 than inFig. 2.

It will be evident that the rearward movement imparted as abovedescribed to the block 10 by the rods 82 is a rectilinear movement thedirection of which is invariable for all shoes. For purposes of thepresent invention, however, the movement imparted to the heel rest bythat movement of the block 76 is a movement the direction of whichvaries for shoes of different styles and for right and left shoes. Fordetermining the direction of movement of the heel rest there is provideda guide bar 88 which extends through a bore in a block 98 slidinglymovable thereon and is secured underneath to a plate 92 supported on theplate 12. A portion of the block extends forwardly and rearwardlythrough a recess 93 in the block 10, as shown in Fig. 3, and otherportions thereof extend upwardly in locations forwardly and rearwardlyof the block I8 and are secured by screws 94 to the plate 66 (Fig. 2).It will therefore be understood that the direction of the movement ofthe heel rest toward the shoe depends upon the direction in which theguide bar 88 extends lengthwise of the shoe. Threaded in this guide baris a stud 96 (Fig. 2) a cylindrical portion of which extends downwardlythrough a hole in the plate 12 to provide an axis about which the barmay be adjusted. Extending downwardly from the front end portion of theguide bar through a curved slot 88 in the plate 12 is a bolt I08 on thelower end of which is threaded a hand wheel I02 for securing the guidebar in any position of adjustment about the axis of the stud 96.

In determining how the guide bar 83 should be adjusted it is necessaryto consider the fact that the toe-end face of every last is insubstantially the same position in the machine and that the longitudinalmedian line of the bottom of the forepart of each last and shoe shouldbe located in the same relation to the edges of the wipers regardless ofthe style or size of the shoe. Figure 5 illustrates diagrammaticallywith reference to three shoe bottom patterns of the same style but ofdifferent sizes the positions which the heel ends of the shoes willoccupy when their foreparts are in the above-described relation to thewipers. The customary manner of pattern grading is such that what may betermed the middle points a at the heel ends of the patterns all lie onthe same straight line b. This line represents the preferred directionof movement of the heel rest 24 as determined by the adjustment of theguide bar 88, so that the guide bar will need to be adjusted only inaccordance with style and not for different sizes. It will beunderstood, of course, that symmetrically opposite adjustments right andleft shoes respectively. To indicate the adjusted positions of the guidebar the plate 72 has thereon a scale comprising two series ofarbitrarily numbered graduations, one for right shoes and the other forleft shoes, arranged to aline with a mark I64 on the front end of thebar. It is contemplated that the operator will have before him a chartindicating by numbers the proper adjustments for shoes of differentstyles. In addition to the adjustment of the guide bar 88, the swing ofthe last requires also a bodily adjustment of the heel rest widthwise ofthe last for difierent styles and for rights and lefts, in order that itwill properly position the heel end of each shoe laterally and willthereby determine the proper position of the toe end of the shoeangularly relatively to the slide. id-,the guide fishes,

as estos.-

of the slide for shoes of different styles. For some.

styles-it may be advisable also to adjust the block 42 .and.theheelrest. to some extent about the vertical axis of the stem 52onthe block.

Asmore fully disclosed inLetters Patent No. 2,1603%, the wipers 2' are,mounted on wiper holderslfltlFig. 6) which are guided for wiper--closing movements laterally of the shoe in curved paths on a wipercarrier IilB under a cover plate I IQonthe carrier. The wipers are helddetachably inplace in slots in the wiper holders by spring pressed pinsIE2 (Figs. 6 and 9) which are slidingly mounted in nipples i it fast onthe wiper holders and extending through curved slot-s II fi; in thewiper carrier, so thatthe wipers may be readily invertedfor use on rightand left shoes and-difierent wipers may be used on shoes of differentstyles and sizes. The wiper carrier I98 is supportednear advance andretract the wipers lengthwise of the shoeona pairof links I I8 which arespaced apart widthwise ofthe shoe, only one of these links being visiblein the drawings. supporting the wiper carrier near its rear end is theupper end of a lever 12% for moving it lengthwise of the shoe, thislever being pivot-ally mounted between its upper and lower ends on afulcrum rod I22 and being provided at its lower with a roll I2lwhichlies in a path cam Hit on a cam shaft 528. The two links H8 areconnected at their lower ends to arms :36 fast on a rockshait I32, andalso fast on this rockshaft is an we provided with a roll I36 which liesin a path cam I38 on the cam shaft I23. Through the arm I34, therefore,the wiper carrier is swung upwardly about its connection with the leverI23 to cause thewipers to wipe the upper heightwise of the last and islater swung downwardly and upwardly to increase and to relieve thepressure of the wipers on the marginal portion of the upper over theinsole.

In proper time relation to the advancing movements of the wiperslengthwise of the shoe the wipers are closed inward laterally of theshoe, first to engage the upper in the upwiping operation and thereafterto wipe its marginal portion inwardly over the insole, by forwardmovement of a slide M9 guided on the wiper carrier M38. The mechanismfor thus operating the slide MEI need not be herein described in detail,since it is constructed substantially as disclosed in Letters Patent No.2,160,846. It includes a bell-crank lever M2 pivotally mounted on thewiper carrier I88 and operated by a cam I43 on'the cam shaft I28 toimpart forward wiper-closing movement to'the slide Hit selectivelythrough one or the other or both of a pair of springs I4 and I536arranged to act on theslide through a rod M8.

Associated with each i with the members 220. On the front end of theshaft 228 is a hand wheel 232 in position convenient for use by theoperator to adjust the wipers as described.

For better insurance that the wipers will apply substantially equalpressures to the upper at the opposite sides of the toe in wiping itheightwise of the last, the construction herein shown is such that thewiper carrier I08 may swing a short distance in a direction widthwise ofthe shoe in response to pressure of one side or the other of the toe onthe corresponding wiper. For this purpose, as shown in Fig. 9a, theconnection between the wiper carrier I08 and the lever I20 comprises arod 234 mounted in the wiper carrier and extending through a bushing 236in the lever, the rod having midway between its opposite ends a convexlycurved portion 238 engaging the bushing and of greater diameter thanother portions of the rod within the bushing. To facilitate the swingingof the iper carrier, moreover, the links I I8 are pivotally connected byforwardly and rearwardly extending pins 246 to blocks 242 which arepivotally connected respectively to the wiper carrier and to the armsI30 by pins 244 extending at right angles to the pins 240. While suchprovision for lateral swinging movement of the wiper carrier isdesirable, for the reason above described, in the upwiping operation, itis further desirable, in operating on flat-lasted shoes, to preventlateral movement of the wiper carrier in response to pressure of theshoe on either of the wipers when the wipers wipe the marginal portionof the upper inwardly over the insole and thus to afford betterinsurance that one of the wipers will not move inwardly over the shoebottom substantially farther than the other. The machine herein shown,therefore, is provided with rolls 246 located opposite to the sides ofthe wiper carrier and arranged to engage cam plates 248 secured on thesides of the carrier. Each roll is mounted on a holder 250 slidinglymounted for movements widthwise of the machine in a member 252 fast onthe frame, the holder being controlled by a light spring 254 which tendsto move it toward the carrier. Threaded in the member 252 is a screw 256having on its inner end a stem 258 extending into a slot 260 in theholder 250 to limit the movement imparted to the holder by the spring.Initially the rolls 246 are so positioned that they are substantially inengagement with the cam plates 248 as shown in Fig. 6, but the springs254 are so light that there is no substantial resistance to such lateralmovement as the wiper carrier may receive in the upwiping operation. Atthe same time when the wipers begin to wipe the upper inwardly over theinsole the forward movement of the wiper carrier causes inclined faces262 on the cam plates 246 to engage the rolls and thus to force themoutwardly against the resistance of the springs 254. In this mannerflanges 264 on the holders 250 are moved into engagement 252, thuspositively insuring that the wiper carrier will occupy a centralizedposition widthwise of the machine as thewipers are moved inwardly overthe bottom of the shoe. Further to insure that the wipers will be movedinwardly substantially equal distances from the edge of the shoe bottomat the sides of the toe, the wiper-closing s1ideI40 is operated throughone or the other or both of the springs I44, I46 with such force thatthe previously mentioned nipples H4 which are mounted on the wiperholders I06 and extend downwardly through the slots H6 in the wipercarrier I08 are moved to positions where they engage the wiper carrierat the forward ends of the slots. Furthermore, the pins I10 carried bythe members I50 are moved to the forward ends of the slots I60 in therods I56.

The cams for advancing and closing the wipers are so formed that afterthe wipers have wiped the margin of the upper inwardly over the insolethey are retracted lengthwise and widlthwise of the shoe substantiallyfrom over the shoe bottom and are then operated to repeat their inwardwipe over the margin of the upper. In coordination with these inward andoutward movements of the wipers they are moved heightwise of the shoe bythe cam I38 in such manner that they follow a path indicated by theseries of arrows in Figs. 14 and 15. That is, after the upwipingoperations they start to move inwardly at such a height as to insureagainst displacement of the edge of the insole, and just after theirwiping edges have passed the extreme edge of the insole (Fig. 13) theyare moved downward to increase their pressure on the upper over theinsole. From that time until they have substantially completed theirinward movements they receive progressively an appreciable upwardmovement. In,

view of the gathers or pleats which develop in the margin of the upperas it is wiped inwardly, this insures that the wipers will not act tooseverely on the upper in the first inward wipe, especially if the bottomof the toe end of the last has a pronounced convex curvature. When thewipers have substantially completed the first inward wipe they areforced downwardly to increase their pressure on the upper. Thereafterthey are raised and are retracted lengthwise and widthwise of the shoeat such a height as to avoid any outward drag on the overwiped upper, asindicated by the arrows in Fig. '15, the margin of the upper being heldby the cement against any substantial retractive movement. They are thenlowered and are moved inwardly again, as also indicated in Fig. 15,without any progressive upward movement such as in the course of thefirst inward wipe and therefore with greater pressure on the margin ofthe upper, after which they are forced farther downwardly to :apply afinal bedding-down pressure to the overwiped margin before they areraised and retracted from the shoe.

Since the wipers 2 as they close present a V-shaped opening between themat the extreme end of the toe, a wiping plate 266 (Figs. 6 and 8) isprovided for bridging this opening, so that the upper over the insolewill be engaged continuously around the end of the toe. This plate has aslightly convex upper face which is seated in concave recesses in thelower faces of the wipers and it tapers to a thin edge near the wipingedges of the wipers. The plate has integral therewith a downwardlyextending arm 268 provided with a pin 210 the opposite ends of whichextend into slots 212 formed in flanges 214 which project forwardly froma plate 216 fast on the wiper carrier I08. A spring 218 seated inrecesses in the plate 216 and the arm 268 tends to swing the plate 266in a clockwise direction with reference to Fig. 8 and thus holds itnormally in a position determined by engagement of its arm 268 above thepin 210 with the plate 216, the lower face of the plate 266 being in thesame plane as the lower faces of the wipers. The slots 212 into whichthe pin 210 extends are slightly elongated in upward and downwarddirections and afford leeway for some slight relative movement of theplate 266 and the wiper ascents ll carrier H16 heightwise of the shoe incase of any upward yield of the wipers ,2 in pressing the pper down onthe insole.

As hereinbefore explained, the device l8, here- 'in termed a retarder,has a pair of fingers 23 curved to embrace the toe end of the last andarranged to clamp the marginal portion of the toe end of the upperoutspread on the wipers to control it during a portion of the lastingoperation. Qne of the fingers 20 is so formed as to extend across theend of the toe and slidingly to engage the other finger in a location atone side of the extreme end portion of the toe, as

indicated at 286 in Fig. 11, so that the fingers maybe relativelyadjusted widthwise of the shoe without interrupting the continuity oftheir engagement with the upper all around the toe. The two fingers aresupported on a rod 282 which extends through and is secured to the lowerend of an upwardly and downwardly extending bar 284 controlled ashereinafter described. Extending upwardly and downwardly at the oppositesides of the lower portion of this bar are two arms 266 also mounted onthe rod 232 and connected together at their lower ends by a web 281 inwhich is a guideway 288 extending widththe rod 'to'vary in that respecttheir relation to; the wipers. For thus adjusting'the arms 28% i thereis threaded in the upper end portion of one 'ofthem a screw 292 which isheld against lengthwise movement by an arm 294 fast on the bar 284, thisarm having a forked and lying between a' flange 296 formed on the screwand a 'knob 298 on the end of the screw. To secure the arms- 286 inadjusted positions a clamp screw 300' is threaded in the bar 284 andextends through a slot 332 in one of the arms.

"For adjusting the retarderfingers Z3 toward e-rt-from each other thereare provided two'latch -members 304 slidingly mounted on a rod 336 whichis secured to the bar 284, these latch members extending into groovesformed in portions of the fingers 20 which are above the rod 282.Threaded on the opposite ends of the rod 366 are nuts 308 eachprovidedwith a flange 3|!) (Fig. which lies in a'groove'formed in the hub of thelatch member 3t3 associated therewith. The latch members are normallyheld connected to the fingers 26 by springs 3l2 which tend to swing themin one direction about the rod 306, but they may be swung against theresistance of the springs by means of arms 3M extending therefrom torelease the fingers and thus to permit the latter to be removed from therod 282 when. it isnecessary to substitute different fingers forshoes'of different sizes.

' The bar 284 which supports the retarder fingers as above described ispivotally supported substantially midway between its upper and lowerends on the forked front end of an arm 3 i 6 (Figs. 1, 10 and 12) whichis loosely mounted on a rockshaft 3l8 supported in bearings in a headcasting 320 mounted on the. top of the frame of the machine. Integralwith the arm 3H5 is another arm 322 which is connected by a spindle 324to one arm 326 of a three-armed lever 328 fast on the rockshaft 3i8. Thespindle 324 is mounted to turn in a-block 330 pivotally'mounted on thearm 322 and is threaded in another block 332 pivotally mounted on thearm 32'6. By'means of a collar 333 and a hand wheel3'36 engaging theblock 336 on its opposite sides-the spindle 324is prevented from movinglengthwise relatively to this block, and accordingly turning movementthereof serves to adjust the arm 3R6 and the bar 284 either in adownward =01 an upward direction to vary .the initial position of theretarder l8 heightwise of the shoe.

Faston one end of the rockshaft 318 is an arm 338 which' is connected*by 'a downwardly extending link 340 to one arm 344 of a bellcrank lever3G6 mounted to turn about a shaft 348. The other arm 3560f thisbell-crank lever is provided with .a roll 352 arranged to engage theperiphery of a cam 3-54 fast on the cam shaft I28. A spring 356connected to the bellcrank lever 346 tends to swing the lever in acounterclockwise direction with reference to Fig. l and thus to move theretarder'lB in a downward direction; This action of the spring 356'issupplemented byithe action of another spring 353 which isxconnectedatone end to a second arm 330 of the three-armed lever 32.8 and at itsother end to a lever 362 which is adjustable to vary the tension of thespring 358 and corresponds to the lever '54 shown in Letters'Patent No.2,354,663. It will thus be seen that at the proper time in the lastingoperation the marginal portion of the upper is clamped on the wipers 2by the retarder under the combined forces of both springs 356 and 358and that the clamping pressure may be varied by adjusting the tension ofthe'spring 358.

In the construction herein shown the cam 354 is so formed and arrangedthat the retarder I8 is initially inits lowest position; so thatitserves, ashereinbefore described, to position the toe end ofthe shoelengthwiseand laterally by engagement with the last when the shoe-ispresented to the machine; "Theretarder is therefore in position to clampthe upper on the wipers when the wipers have been moved upwardly farenough to cause this action to occur; as illustrated in Fig. 12, afterwhich the wipers may start to lift the retarder. Instead ofrequiring thewipers thereafter to lift the retarder against increasing resistance'ofthe springs 356 and 358, the cam 354 has on its periphery a gradualrise'c' arranged to act on the roll-352 to lift-the retardercoordinately with the upwiping movement of the wipers, so that aftertheupper has been clamped with the'desired'pressure the pressure thusapplied will remain substantially uniform -as the wipers are movedfarther upwardly. The time when this rise on the cambecomes effectivethus to act on the retarder may be varied by a screw 364 which'isthreaded in an arm 366 integral with the arm 338 and is arrangedto'engage the head casting 326. That is, by means of this screw the roll352 may be spaced more or less initially from the periphery of'the camto vary the time when the rise 0 on the cam begins to. act on the'roll.It will be evident that if the roll is thus spaced initially from thecam and the retarder is initially at the same height the wipers willlift the retarder farther before the cam begins to lift it andaccordingly the force with which the upper is ultimately clamped betweenthe retarder and the wipers will be'greater than if the roll isinitially in engagement with the cam. Such adjustment of the screw 364will, of course, vary the position of the retarderheightwise of the anut 388 13 shoe, but this may be compensated for by turn ing the spindle324.

As the retarder is thus moved upwardly it is controlled with respect tomovement lengthwise of the shoe by a cam plate 368 having therein a slot318 in which is positioned a roll 312 mounted on the upper end of thebar 284. This cam plate is pivotally mounted on a pin 314 on the headcasting 328 and has pivotally connected to its lower end a rod 316extending rearwardly through an opening in the casting. Threaded on thisrod are a collar 318 and a nut 388 arranged to engage the castingrespectively on its inner and outer faces for adjusting the cam plate368 about the pin 314. By adjustment of the cam plate, therefore, theinitial position of the retarder with respect to movement in directionslengthwise of the shoe may be varied. To permit a variation in thisrespect of the initial position of the retarder independently of the camplate 368 the connection between the bar 284 and the arm 3I6 comprisesan eccentric 382 (Figs. and 12) on which the bar is mounted, thiseccentric being formed on a stud 384 adjustable in a bearing in the arm3I6. To hold the eccentric in adjusted position there is mounted in thearm a pin 386 provided in one side with a curved recess (not shown) intowhich one side of the stud 384 extends, the pin having threaded on itsupper end for moving it lengthwise to locl: the stud.

The retarder I 8 is preferably so adjusted about the rod 282 by means ofthe screw 292 (Fig. 12) that it clamps the upper on the wipers first atthe end of the toe, the wipers occupying at this time a position inwhich they are somewhat inclined lengthwise of the shoe. As the wipersare thereafter swung farther upward they arrive in positions in whichthe retarder is effective to clamp the upper upon them also along thesides of the toe. It will be evident that by means of the screw 292 thepressures applied by the retarder to the upper at the end and the sidesof the toe respectively at the completion of the upwiping operation maybe relatively varied as desired.

Associated with the retarder I8 is a holddown 398 for engaging themarginal portion of the toe end of the insole to assist in preventingits displacement as the wipers wipe the upper upwardly and begin to wipeit inwardly over the edge of the insole. This holddown comprises a pairof curved fingers 392 (Fig. 11) pivotally mounted on a stem 384 (Fig.13) which extends downwardly from a block 396 and held in place bythehead of a screw 398 threaded in the stem. A spring 488 mounted inrecesses in the fingers and held in place by pins (not shown) extendingwithin it from the fingers tends to swing the fingers outwardly andthereby holds them against the inner faces of the retarder fingers 28.Accordingly the holddown fingers assume positions determined by theadjustment of the retarder fingers widthwise of theshoe and require noseparate adjustment for shoes of different sizes. The block 396 ispivotally mounted on a pin 482 extending widthwise of the shoe in thelower end of an upwardly and downward- 1y extending slide 484 mounted inguideways in the arms. 286. The holddown 398, therefore, may adjustitself to the bottom of the shoe about the pin 482. When thereis no.shoe in the machine it is held in a definite position with respect tomovement about the pin by a spring-pressed pin 486 mounted in the slide404 and having on its lower end a head488 arranged to engage a flat faceon the block 396. The slide 484 is under control of a spring 4I8 whichtends to move it downwardly, the spring being seated at its upper endagainst a cap member 4I2 which partially incloses it and which issecured on the upper ends of the arms 286. To hold the lower end portionof the spring in place a pin M4 extends upwardly within it from theslide 484. For determining adjustably the height at which the holddown398 is initially positioned there is provided a bell-crank lever H5pivotally mounted on a pin M8 in the block 6 (Fig. 12) with one of itsarms 428 in supporting engagement with the lower face of a projection422 on the lower end of the slide 484. The other arm 424 of thebell-crank lever is forked to straddle a screw 426 which is rotatable inthe block 6 and has a hand wheel 428 thereon for turning it. Threaded onthe screw is a nut 438 in contact with the arm 424 and prevented fromturning by engagement with the block 6. A spring 43I acting on the arm428 holds the arm 424 at all times against the nut. The slide 484 ispreferably so adjusted by the screw 426 that the lower faces of theholddown fingers 382 are slightly lower than the lower face of theshoe-positioning plate 4 when there is no shoe in the machine, so thatwhen the toe rest 22 is moved upwardly the holddown will be liftedslightly against the resistance of the spring 458 by engagement of theshoe therewith, thus insuring that it will be effective to press themarginal portion of the insole down on the last.

For withdrawing the holddown 398 from the shoe to clear the wipers asthey wipe the upper inwardly over the insole a third arm 432 of thethree-armed lever 328 is arranged to engage a nut 434 held in adjustedposition on a rod 438 by a lock nut 438 (Fig. 10), the lower end. of therod 436 being pivotally connected to an arm 448 projecting from theslide 484. The nut 434 is initially spaced from the arm 432'far enoughto permit the upward movement of the retarder I8 with the wipers in theupwiping operation Without disturbing the holddown 398. When the wipers,as they begin to wipe the upper inwardly over the insole, arrive inpositions substantially as shown in Fig. 13, an abrupt rise at (Fig.1)on the cam 354 moves the retarder I8 quickly upward away from theWipers, and at the same time the arm 432 acts on the slide 484 to movethe holddown 398 upwardly out of the paths of the wipers.

The means for driving the cam shaft I28 and for starting and stoppingthe cycle of operations of the machine are, except as hereinafter noted,of the same construction as shown and described in Letters Patent No.2,160,846. Briefly, there is fast on the cam shaft a gear Wheel 442(Fig. 1) engaged and driven by a worm 444 which is fast on a shaft 448at right angles to the cam shaft. Normally rotatable about the shaft 446is a clutch member 448 driven continuously by an electric motor 458, andconnected to this shaft to turn therewith is a cooperating clutch member452 movable lengthwise of the shaft into or out of frictionalengagementwith them ember 448, the member 452 being held in suchengagement when the machine is operating by means of a spring 454. Towithdraw the member 452 from the memher 448 and thus to stop theoperation of the machine there is provided a yoke member 456 mounted forswinging movements and connected to the hub of the member 452. Connectedto the since it is held yoke member to swing therewith is an arm 458(Fig. 16) on which is secured a latch member 468 normally engagedunderneath by a shoulder 461 formed on a block 462 to hold the yokemember in such a position that the clutch member 452 is out ofengagement with the member 44%. The block 462 is mounted on an arm 484which is pivotally supported at its upper end on one arm of a bell-cranklever dSB pivotally mounted at 468 on a lug on the frame of the machine.The other arm' of this bell-crank lever carries a roll 41!] engaged by apath cam 112 on the cam shaft !28. A spring M4 connected to the arm 4S4tends to swing it in a rearward direction to hold the block 462 inoperative relation to the latch sec. The lower end of the arm 464extends through a slot formed in a substantially horizontal forwardlyextending bar 416 and below the bar carries a pin 4T8 arranged to engagea shoulder 48!] on the bar. The bar 416 is pivotally connected at itsfront end to an arm 582 fast on a rockshaft 684, and a spring E86connected to this arm tends to swing it in a rearward direction and thusto hold the rear end of the bar 416 against a stop 488. The rear end ofthe bar Q16 is, moreover, supported on the upper end of a screw 49!] andis held down on this screw by a spring 492. Also fast on the roclzshaftA34 is a treadle 495. It will thus be seen that when the treadle isdepressed the bar 416 is moved in a forward direction and down by thespring 492 it swings the arm 46% forwardly by engagement of its shoulder48B with the pin M8 to disconnect the block 462 from the latch ist. Thispermits the spring 455 to force the clutch member 352 into engagementwith the member M8 to start the operation of the machine. For bringingthe machine thereafter to a stop, the arm 554 is lowered by the actionof the earn 512 on the bell-crank lever 456, thus disengaging the pin H3from the shoulder 480, if the operator has not released the treadle, andpermitting the arm to be swung by the spring 474 to carry the shoulder66! again under the latch member diiil, after which the arm 464 islifted to swing the yoke member Q58 in the direction to disconnect theclutch members from each other. In the construction herein shown the cam412 is so formed as to bring the machine thus to a stop not only at theend of the cycle, but also before the of the cycle when the wipers havecompleted their second inward wiping movements, to allow more time forthe cement to set while the upper is held under pressure by the wipers.The operator thereafter starts the machine again by depression of thetreadle to cause it to complete the cycle.

Under some conditions it may not be necessary to bring the'machine to astop as above described to permlt the wipers to dwell on the margin ofthe upper. The machine herein shown is therefore provided with means foroptionally rendering the cam M2 ineffective to stop the machine beforethe end of the cycle. For this purpose a bell-crank lever A95 is mountedto swing about the same axis as the yoke member 456 but independentlythereof, one arm 498 of this lever carrying a roll 5% engaged by aperipheral cam 582 on the cam Shaft L28. A spring 5% connected to theother arm 5% of this bell-crank lever holds the roll 595 against thecam. The arm 5% is forked to provide a guideway for an upwardly anddownwardly movable slide 5138. Threaded in 2; lug M on this slide is thelower end of a rod '5l2, the upper end of which is connected by a link Mto one arm of a hand lever 516 pivotally mounted at M3 on theframe ofthe machine. By the hand lever M6, therefore, the slide 508 may be movedupwardly or downwardly along its guideway in the arm 5% to one or theother of two different positions determined by .asprin gpressed pin 52%on the lever and two holes 522 formed in the frame to receive the pin.As the parts are shown in Fig. 1 the slide 568 is in its lowermostposition with its lower end portion directly at the 526 on the arm @5 2.The cam 5&2 is so formed that before the cam M2 becomes effective tostop the machine prior to the end of the cycle it swings the bell-cranklever 496 in a counterclockwise direction with reference to Fig. 16 andthereby causes the lower end of the arm 5% to engage the pin 52 i andswing the arm tilt in a forward direc tion so that when the arm israised by the cam M2 the shoulder dill will not engagethe latch its and,therefore, will not stop the machine. It will be understood that the cam5 92 will perunit the bell-crank lever 496 to by the spring are beforethe end of the cycle,so that it will not interfere with the stopping ofthe machine at the end of the cycle. If it is desired that the machineshall come to a stop prior to the end of the cycle at the time when thewipers are over the bottom of the shoe, the operator moves the lever 515to withdraw thelower end of the slide 5% from its position at the rearof the pin 5%. With the slide thus withdrawn, it will not engage the pinwhen the bell-crank lever 49% is swung as above described by the cam 5M,and accordingly the cam M2 will not be prevented from bringing themachine to a stop prior to the end of the cycle.

The manner of aeration of the machine, in so far as it is of interestwith reference to the present invention, will now be briefly summarized.It will be understood that before the shoes come to the machine the toeend p'ortionsof the uppers are trimmed. as customary prior to cement toelasting, so that for the most part the margin of the outer layer only ofthe upper materials of each shoe will lie next to the insole and will.be secured thereto by the cement previ viously applied to the shoe.Prior to the use of the machine on shoes of a given style the op eratoradjusts the bar 8% which guides the heel rest in its movement toward theshoe by swinging the bar laterally to the position required for shoes ofthat style, which may be indicated on a chart, making the properadjustment by reference to the scale on the plate '52. If the shoesimmediately to be operated upon are right shoes the adjustment is madeby reference to the right-hand portion of the scale andif they are leftshoes it is made by reference to the lefthand portion of the scale. Theoperator also adjusts the slide 46, along the guide it to a positionwhich may likewise be indicated on the chart, bringing one end or theother of the slide into registration with the proper scale mark on theguide. In this manner the heel rest is properly positioned initiallywidthwise of the shoe relatively to the guide bar 918. If desirable,moreover, the heel rest may be adjusted about the vertical axis of thestem 52 or in an upward or a downward direction along. the curved pathdetermined by the guideways 38 (Fig. 2).

In presenting the shoe to the machine the operator moves it to aposition in which the bottom of the fore'part of the insole is inengagement with the plate 4 and the holddown 3% and the toe end face ofthe last is in engagement with rear of a pin 524 mounted ina lug.

be swungreversely the curved fingers 20 of the retarder I8, thesefingers having been preliminarily adjusted in accordance with the widthof the shoe and having by their adjusting movements correspondinglyadjusted the insole holddown fingers 392. The retarder l8 accordinglydetermines the position of the shoe lengthwise and the position of itstoe end laterally. After thus presenting the shoe the operator startsthe machine by depression of the treadle 494 (Fig. 16). Substantially atthe beginning of the cycle of operations the toe rest 22 is movedupwardly to clamp the shoe yieldingly against the plate 4 withcomparatively light pressure. If the holddown 390 is so adjusted thatthe insole-engaging faces of its fingers 392 are initially slightlylower than the insole-engaging face of the plate 4, it is raised by theshoe as the shoe is forced against the plate 4 by the toe rest. Shortlyafter the upward movement of the toe rest the rods 82 are movedrearwardly to carry the heel rest 24 into engagement with the heel endof the shoe. The heel rest is thus moved in the direction determined bythe adjustment of the guide bar 88 and upon engagement with the shoedetermines the position of the heel end of the shoe laterally. In thismanner, as hereinbefore explained, the toe end of the shoe is properlypositioned angularly in relation to the Wipers which are to operatethereon. If the heel rest, upon such engagement with the shoe, causesthe heel end of the shoe to move a short distance laterally in onedirection or the other, such movement of the shoe is facilitated byreason of the fact that the toe rest, as above explained, is at thattime holding the shoe with comparatively light pressure.

In proper time relation to the operations above described the wipers 2are advanced and closed about the toe end of the shoe and are swungupwardly to wipe the upper heightwise of the last. When they arrive inthe positions indicated, for example, in Fig. 12 they clamp the upper,which is outspread over their top faces, against the retarder l8 and maythen start to lift the retarder against the resistanceof the springs 356and 358. At a time, however, depending upon the adjustment of the screw364 (Fig. 1) the rise on the cam 354 becomes effective to lift theretarder coordinately with further upward movement of the wipers whilemaintaining the clamping pressure on the upper substantially uniform.During the upwiping operation the wiper carrier I68, as hereinbeforeexplained, may swing slightly in one direction or the other widthwise ofthe shoe relatively to its operating lever I26 in response to pressureof one side or the other of the toe on the corresponding wiper to assistin equalizing the pressures of the wipers on both sides of the toe.

- After the completion of the upwiping operation the wipers are furtheradvanced and closed to wipe the marginal portion of the upper inwardlyover the insole, the retarder at first still maintaining its clampingpressure on the upper. Shortly after the beginning of this inward wipe,when the wipers have arrived substantially in the positions illustratedin Fig. 13, the abrupt rise d on the cam 354 (Fig. 1) moves the retarderupwardly away, from the wipers to release the margin of the upper andmoves the holddown 390a1so upwardly awayfrom the insole. Atapproximately the same time the force applied to the toe rest 22 isincreased to supportthe shoe morefirmly against downward pressure of theWipers. The wipers begin their inward wiping movements at such a heightas to insure against displacement of the edge of the insole, and whenthey arrive substantially in the positions illustrated in Fig. 13 theyare moved downwardly to increase their pressure on the upper over theinsole. Thereafter, as they are moved farther inwardly, they receiveprogressively an appreciable upward movement until they havesubstantially completed their inward Wipe on the upper to prevent themfrom acting too severely on the gathers or pleats which develop in themargin around the end of the toe. When the wipers have substantiallycompleted their inward movements they are forced more firmly down on themargin of the upper. The manner in which the wipers thus act on theupper-in wiping it inwardly is indicated by the directions of the arrowsin Fig. 14. Substantially at the beginning of this operation the wipercarrier I08 is centralized with respect to lateral movement and islocked against such movement by the action of the cam plates 248 on theroll holders 250 (Fig. 6). After the first inward wipe the wipers areraised and retracted and are thereafter moved downwardly and areadvanced and closed a second time in wiping engagement with the upper asillustrated by the arrows in Fig. 15, their downward pressure on theupper being again increased at the end of the second inward wipe. Thewipers are thus moved inwardly the second time without any progressiveupward movement such as they receive in the course of the first inwardwipe and therefore with greater pressure on the margin of the upper.

If the hand lever 5l6 is positioned as shown in Fig. 16 the wipers arethereafter lifted and retracted from over the shoe and the parts of themachine are returned to their starting positions, the machine coming toa stop only at the end of the cycle, since the cam 502 by its action onthe bell-crank lever 496 prevents the stopping of the machine prior tothe end of the cycle, as hereinbefore explained. If, however, the handlever has been moved to retract the slide 508 from its position at therear of the pin 524, the machine comes to a stop with the wipers in thepositions indicated in Fig. 15 to allow more time for the cement to setwhile the margin of the upper is held by the wipers. In that case theoperator starts the machine again after the desired interval bydepression of the treadle 494 to cause it to complete the cycle.
